Watts/grams ratio

Another thing to consider is how long the plant is in 12/12. If I am comparing the yield of different cuttings under the same light I usually look at grams/watt/8 weeks. Obviously it makes a huge difference if you have 6.5 week and 10 week girls you are trying to compare the cost of growing.

Yep, some of my sativas are almost 10 weeks so they yield very lilttle per watt compared to my 8 week finishing indica strains.

i started a midgrade seed as an experiment. i had 4 flowering plants a few weeks in and tried to throw a bunch of seeds into soil, 22 of them to be exact. most stretch too much some died. and 2, yes only 2, were worth keeping. one turned male. the other ive had in 12/12 for around 10 weeks or so and it looks like its halfway through flowering. anyone else had to flower for more than 10?

My chernobyl from subcool was 55-60 day flowering time& its dead on! My outdoor went 9,but were not talkin'bout outdoh!

tis what i mean, i believe it to be sativa, but from a random seed laying around, who knows? leaves just look it. im hoping in the next two weeks shell finish. of course it will only be like a quarter, but you take a mid seed, grow it and it has no seeds and smells fucking dank....ill smoke the shit outta that quarter lol.

how does flowering time effect grams/watts?wattage doesnt make flowering faster,just more productive,right? Flowering time is strain specific.grams/watts remains same-even if it takes longer to finish.right or wrong?length of flower time just effects cost of grow? Thats my thoughts anyways.

the only time i can think of the yield changing from that would be comparing clear tric harvest with amber tric harvest. might get a small push at the end.

I am doing a perpetual grow so I keep track of how many grams are produced over a 2 month period, that is about 9 weeks which is about the time it takes for most strains to flower. I'm running at about .75 grams per watt. I do a combo of DWC and soil and just run base nutrients (Sensi A & B). I just got some big bud and am going to experiment with adding that into the mix.

VERY easily! If you get 2 grams a watt for 8 weeks, that turns out to be 25 grams for a 100 week period per watt. If you get 2 grams a watt for 10 weeks, you get 20 grams for a 100 week period per watt. AKA 20% less yield.

That's like selling for $5000 a pound, and only getting $4000 out of it each time because you have to use the same flower space longer for plants for the same money.

My last run i flowered a couple of afgooey's and a NYCD for 101 days. 14 1/2 weeks.

Grams a watt is a nice for rule of thumb type mesurements but common scense says that a veg time of 2 weeks would produce less than a 4 week veg.

Watt per kw/hr is more accurate.

A 2 week veg time may not produce less than a 4 week veg time. If you dont have enough light penetration for the 4 week veg plants, you'll just get long stretchy buds rather than long solid colas. Your rule is generally correct, but a 4 week veg time for most RIU'ers without 1000w lamps and 5 feet of space above the buckets would be worse than a 2 week veg.

You can only get as much bud as you use light for of course.........

Okay, I think your splitting hairs. Let me rephrase...

Your gr/watt will definitely be influenced by root mass at time of 12/12, and root mass is directly influenced by veg time. Therefore, gram/watt is definitely influenced by veg time.
